LEVEL AND ELUMB.

Application filed December 27. 1923.. Serial No. 525,000.

instead of the well known spirit level, the

general object of the invention being to provide a rotary weighted member having indications thereon which will revolve on its axis when the work piece is not level, the indications giving the amount the work piece is out of plumb.

Another object of the invention is toenclose the member in a casing so that the same will be protected from dirt, dust and the like and tc-provide the casing with several transparent parts so that the rotary member can be seen from diiicrent positions.

This invention also consists in certain other features ofconstruction and inthe combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawil'ig's and specifically pointed out in the appended claim.

' In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Y Figure 1 is a plan View of the device.

Figure 2 is an elevation thereof.

Figure 3 is a section on line 3-3 of Figure 1.

Figure 4 is a detail view showing the means for adjusting the weight in the ro tary member.

Figure 5 is a perspective view of the sleeve 5. V

Figure 6 is a view of the ring member 11.

Figure l is a view of the ring member which carries the graduations.

In these views 1 indicates the stock which is provided with a recess 2 to receive the of the rotary member. A sleeve 6 passes through the member and is secured thereto and this sleeve is rotatabiy mounted on the shaft. A ball race 7 is secured to each side of the rotary member for receiving the balls 8, said halls being held in the race bv the washer 9 which engages the. shohlder formed at the junction of the reduced screw threaded end of shaft 5 with its major part. A cover 10, of transparent material, covers each end of the recess 2, said cover being secured to the stock by the ring 11. Each cover is provided with an opening 12 through'which the screw threaded end or the shaft 5 passes, rubber washers 13 being located on each side of the cover to protect the same. The parts are held in assembled position by the nuts 14. engaging the screw threaded ends of the shaft 5.

A. weight 15 is adjustably secured to the rotary member by means of the bolts 16 and the slots 17 and openings 18 are formed in said member to facilitate the movement of the member by the weight. The sides of the member are provided with arrows 1'9 whichv z i are associated with stationary graduations placed on rings 19, which are held in place by rings 11 and which can be seen through the transparent covers 10 and the circumference of the rotary member is provided with the graduations 20 which may he secn through a Window 21 in the upper edge ot the stock. Thus the device can be read from either side and from the top.

t is thought from the foregoing: description that the advantages and novel features of my invention will be readi1 apparent.

I desire it to be understood that I may malte changes in the construction and in the combination and arrangement of the several parts, provided that such changes tall within the scopeof the appended claims.

What 1' claim is A tool of the class described comprising a stock having a recess therein and a window in its upper edge communicating with the recess, side plates connected with the stock and arranged at the ends oi the recess, each plate having an upwardly extending narrow part, a shaft having its ends carried by said narrow parts, a hollow circular member rotatably-s'upported by said shaft said member having curved slots in the error Hit) its a Weight arranged in said belts assling through the sidts and the Weight for adjustably c0n- Zhe \"veight to the member, transiteemhers connected with the stock g rhs 11015 of the recess, indicating zhe enfeumference ef the circular Y r adept-ed to appear through the window, indicating) marks on the ends of the circular mem or adapted to appear 10 through the transparent members, rin members held in the ends of the recess an having graduations thereon for cooperating with the marks on the ends of the member.

In testimony whereof I aifix my signature.

ROBERT ZIEGLER.
